Radiator support structure

Abstract

A radiator support structure in which in case a radiator is supported in a housed state between down pipes, the effective area of the radiator can be increased. A radiator is supported in a housed state between down pipes branched in two directions from a head pipe and extended downward. An upper part support is provided on the upper surface of the radiator, a lower part support is provided on the lower surface of the radiator, and the radiator is supported by the down pipes via the upper part support and the lower part support.

1. A radiator support structure for a vehicle that supports a radiator in a state in which the radiator is housed between a head pipe of a body frame supporting a front fork and a down pipe which branches into two downward extending parts, comprising:
 an upper part support provided on an upper surface of the radiator; and 
 a lower part support protruding downward on one side of a lower surface of the radiator in the direction of the width of the vehicle, wherein the radiator is supported by the down pipes via said upper part support and lower part support, the radiator extending parallel to and being disposed between the two downward extending parts; 
 a bracket extending rearwardly from at least one of the downward extending parts; 
 a supporting member including a main plate attached to the bracket and a supporting plate extending forward from the main plate to a position between the two downward extending parts for supporting the radiator 
 wherein an engine is attached to the main plate, thereby causing the engine to be supported by the down pipe. 
 
   
   
     2. The radiator support structure according to  claim 1 , wherein the upper part support is pair a of right and left upper part supports protruding upward, said pair of upper part supports being bolted to an upper installation member supported by the down pipe, thereby fixing the upper part of the radiator to the down pipe. 
   
   
     3. The radiator support structure according to  claim 1 , said supporting member being provided with a supporting hole fitted with a grommet, wherein the lower part support of the radiator is inserted into said grommet, thus enabling the radiator to be supported by the down pipe. 
   
   
     4. The radiator support structure according to  claim 1 , further comprising an exhaust port provided on a side of the lower surface of the radiator which is opposite the one side of the lower surface of the radiator where the lower part support protrudes downward. 
   
   
     5. A radiator support structure for a vehicle that supports a radiator in a state in which the radiator is housed between a head pipe of a body frame supporting a front fork and a down pipe which branches into two downward extending parts, comprising:
 an upper part support provided on an upper surface of the radiator; and 
 a lower part support protruding downward on a lower surface of the radiator, said radiator being substantially rectangular in shape and being supported by the down pipes via said upper part support and lower part support, and said radiator being disposed between the two downward extending parts in a manner such that right and left sides of the radiator are parallel to the two downward extending parts, said radiator overlapping a whole length of the two downward extended parts of the down pipe; and 
 a bracket extending rearwardly from at least one of the downward extending parts; 
 a supporting member attached to the bracket, 
 the supporting member including a main plate for attaching an engine of the vehicle, the main plate being bolted to the bracket, thereby causing the engine to be supported by the down pipe, 
 the supporting member also including a forward extending portion for supporting said lower part support. 
 
   
   
     6. The radiator support structure according to  claim 5 , wherein the upper part support is a pair of right and left upper part supports protruding upward, said pair of upper part supports being bolted to an upper installation member supported by the down pipe, thereby fixing the upper part of the radiator to the down pipe. 
   
   
     7. The radiator support structure according to  claim 5 , wherein the supporting member attached to the bracket supports an engine by the down pipe. 
   
   
     8. The radiator support structure according to  claim 5 , said supporting member being provided with a supporting hole fitted with a grommet, wherein the lower part support of the radiator is inserted into said grommet thus enabling the radiator to be supported by the down pipe. 
   
   
     9. The radiator support structure according to  claim 5 , wherein the lower part support of the radiator is fitted to the forward extending portion, thereby causing the lower surface of the radiator to be supported by the down pipe. 
   
   
     10. The radiator support structure according to  claim 5 , wherein the upper part support of the radiator is attached with a bolt, the bolt having an axis extending in a longitudinal direction of the vehicle. 
   
   
     11. A radiator support structure for a vehicle that supports a radiator in a state in which the radiator is housed between a head pipe of a body frame supporting a front fork and a down pipe which branches in two directions and extends downward, comprising:
 an upper part support provided on an upper surface of the radiator; and 
 a lower part support protruding downward on a lower surface of the radiator, 
 a bracket extending rearwardly from at least one of the downward extending parts; 
 a supporting member attached to the bracket, 
 wherein the radiator is supported by the down pipes via said upper part support and lower part support, and 
 wherein said radiator is substantially rectangular in shape and overlaps a whole length of a downward extended part of the down pipe, 
 wherein the lower part support is supported by the supporting member, 
 wherein the lower part support is provided on one side of the lower surface of the radiator in the direction of the width of the vehicle, and 
 said supporting member also serving as an engine hanger for supporting an engine of the vehicle. 
 
   
   
     12. A radiator support structure for a vehicle that supports a radiator in a state in which the radiator is housed between a head pipe of a body frame supporting a front fork and a down pipe which branches into two downward extending parts, comprising:
 an upper part support provided on an upper surface of the radiator; and 
 a lower part support provided on a lower surface of the radiator, wherein the radiator is supported by the down pipes via said upper part support and lower part support; and 
 a bracket extending rearwardly from at least one of the downward extending parts; 
 a supporting member attached to the bracket, 
 wherein said lower part support is supported by a forward extending portion of the supporting member, said supporting member also serving as an engine hanger for supporting an engine of the vehicle, and 
 wherein the radiator is mounted between the two downward extending parts and on a plane formed by the two downward extending parts.
